HP SIM 5 contents cannot be seen by login w/ new account after service account changed

Hi, I encountered a problem after I changed service account of HP SIM 5. I changed original Administrator service account to another new account and all services work fine. After I login HP SIM w/ the new account, there's nothing in HP SIM contents. Seems that I have to re-discover all machines. However, the contents still can be seen if I login w/ the original Administrator account.

Does anybody can tell me how to let the new account to see these contents that Administrator account can see? Thanks in advance.
